APPARATUS FOR TREATING EMULSIFIED OIL.

Applieationfiled August 21, 1920, Serial No 405,103. Renewed May 28, 1928.

This invention relates to improvements in apparatus for treating emulsified oil and refers more particularly to an apparatus and process in which emulsified petroleum oils, as for example, emulsified Mexican and (alifornia crudes, may besimultaneously dehy drated and distilled. 1

In the drawings, Fig. 1 is a side elevation,

I broken away and shown in dotted lines, of

our improved apparatus. Fig. 2 is a sectional View taken on lines AA of Fig. 1.

Referring, to the drawings, 1 designates a firebox in which is mounted a still, 2, as for example, of the shell type. Oil is delivered from any suitable source of supply through the feed line, 3, controlled by valve, 4, and the liquid residueis drawn off through line 5, controlled by valve, Vapors pass out of the still through the vapor line, 7 pro vided with throttle valve, 8, which line. 7, connects to watercondensercoil, 9, leading to receiver, 10. The'receiver, 10, is provided with liquid drawofi line, 11, controlled by valve, 12, and may be provided with gas outlet pipe, 13, controlled by throttle valve, 14.

As a feature of the invention, means are provided for gently or mildly agitating the contents of the still. This is accomplished by means of the rotating blades or paddle members, 15, carried by longitudinally extending shaft, 16, which shaft, 16, is provided with a driving pulley, 17, connected to any suitable source of power. a

The still is heated by means of the gas burners, 18, which extend circumferentially along the sides of the still adjacent the vapor space thereof, the interfaces of the burners being slotted, as shown, at 19, in order to more uniformly heat the still throughout its length. The'arrangement is such as to produce a surface heating of the oil. The upper part of the oil body is primarily heated causing a continuous distillation, in which,

tendsto facilitate and hasten the distillation I by successively presenting different portions of the oil body to the surface to be distilled therefrom without at the same time causing the still to foam over. The process may be operated at atmospheric pressure so as to simultaneously dehydrate and fractionate the oil. A certain amount of cracking may also take place, due to the localheating of the vapor space of the still. i i

As a modified manner of carrying out the process, the emulsified oil may be both dehydrated and cracked under a pressure of pounds to the square inch or more by suitably regulating the valve shown. The pressure may be maintained on the entire system during both distillation and condensation. A differential pressure may be maintained by suitably regulating valve, 8.

- We claim as our invention:

1. In an apparatus for treating emulsified oil, 'the combination with a still, means for feeding a bulk supply of oil to the still, said still having a vapor space above the oil charge, of a burner extending lengthwise of said still and having gas discharge orifices throughout its length for applying the entire heat to the vapor space of the still, and means for agitating the liquid oil in the still below the surface thereof, said means comprising a rotary agitator extending through the still.

2. In an apparatus for treating emulsified oils, the combination with a shell still adapted to receive a bulk supply of oil'and having a vapor space therein above the oil level in said still, of an elongated burner extending lengthwise of said still on each side thereof for producing heating a'ses discharging against the vapor space of t 1e still to heat the surface of the oil therein to the maximum temperature, and a mechanical agitator'immersed in the oil in the still for agitating said oil during distillation.

3. An apparatus for simultaneously dehydrating and fractionating emulsified oils, comprising a furnace, an elongated cylindrical shell located in said furnace, a pair of burners co-extensive with said still and arranged to admit the flames adjacent the wall of said still in a plane above the highest liquid level in said still to distil the oil onl from the surface thereof, a rotary sha mounted in the "lower portion of said still and substantially co-extensive therewith, agitating fan members carried by said shafts and means to rotate said shafts to successively force different portions of the oil body to the surface. to be distilled therefrom.

4. An apparatus for simultaneously dehydrating and fractionating emulsified oils, consisting of an elongated cylindrical shell still located in a furnace, a pair of burners mounted in said furnace to apply heat to the Wall of said still throughout substantially its entire length, in a plane above the highest liquid level maintained in said still, an elongated rotary mechanical agitator mounted in the lower portion of said still, means for rotating said agitator to successively force 1 different portions of the oil body to the surthe distillate from the condenser to said re- 15 oeiver.
